摘要
A pulse width modulation (PWM) control method for a five-level inverting circuit is provided. The five-level inverting circuit includes a first capacitor, a second capacitor, a third capacitor and first to eighth switch branches. In this PWM control method, the control logic is set to enable the first and fourth switch branches to be turned on in a complementary manner, the second and fifth switch branches to be turned on in a complementary manner, the third and sixth switch branches to be turned on in a complementary manner, and the seventh and eighth switch branches to be turned on in a complementary manner, and enable the first and second switch branches to be turned on in an interlocking manner, and the sixth and fifth switch branches to be turned on in an interlocking manner.
